As fate would have it, I go on a bike ride the day after ordering a PMB insert and the stock baffle starts rattling all about. I check it and it is extending out about 1" from the pipe. I tried to remove the bolt to just yank the sucker out, but the bolt appears stripped or something--it just turns and turns. I assume that it is just a bolt and that the threads on it or the pipe are screwed up. Am I on the right track? ANd if it is the pipe screws that are messed up, is there a fix or do I need a new pipe?
